[PULL 07/12] virtiofsd: Add attr_flags to fuse_entry_param

["Dr. David Alan Gilbert (git)" <dgilbert@redhat.com>]

From: Max Reitz <mreitz@redhat.com>

fuse_entry_param is converted to fuse_attr on the line (by
fill_entry()), so it should have a member that mirrors fuse_attr.flags.

fill_entry() should then copy this fuse_entry_param.attr_flags to
fuse_attr.flags.
